E39 (1997 - 2003)
The BMW 5-Series (E39 chassis) was introduced in the United States as a 1997 model year car and lasted until the 2004 when the E60 chassis was released. The United States saw several variations including the 525i, 528i, 530i and 540i. -- View the E39 Wiki

i didn't know lowes sold orange a/c flex pipe. but really, if you suck water up that filter kiss you motor good bye. belive us, there have been a few that have dainan cia's and sucked water up.
also even thought your motor sounds good, how much cold air will pass through, given it's a fabric pipeing.

Well that settles it, I guess. Two of your friends say it adds power so it must. To hell with facts and measurements.

You might want to rethink your driving habits before you hurt an innocent bystander. If you want to wrap yourself around a tree then that is your business but I don't think you want to be responsible for injuring or killing some innocent person.

That was a very revealing post.

Take your car to a track next time.

Well I don't have money to go to track every time I want to go over 70mph because the closest real track is 160 miles away and it costs 200 to get in so the total price would be just over 350 just to go and race. Don't get me wrong I love going there and I know it's much safer and actually more fun on a track but my current finances don't allow me to do that

Then dear god don't endanger the rest of us if you can't afford it. I absolutely love to race and drive cars to the limit. For that I have my 67 mini. I can out handle a Ferrari, but can't out accelerate a Civic. If you want to hone your skills, learn to drive a slower car to it's limit. Going fast in a straight line takes no skill. I'm all over improving the performance of your car. But it takes years of racing and research to do so correctly.

The guys on here dont care if you do 130+ on a public road if the conditions are safe.
They just dont want you racing people on public roads.

Well I used to have a 2000 civic auto and I DID push it way above ITS limits. (It was running on 3 cylinders because EVERY day i would go past 7K..I know the redline on it is pretty crappy).I crashed it into rocks, drove off the hills and my friend crashed it into a hill once. With its setup (coil over springs and 215 tires) I outhandled MANY cars on the mountain roads including M3s, RX8, AE86s, EVO9s and STIs. The only car I relly lost to was a EVO10 fully tuned up.

That car could destroy my 540i on that road and probably any other bmw on this forum. But again, on a track, most bmws would just leave the civic behind.

My friend (2008 accord) and I were side by side on cruise control going home from a local mountain race and it was like 2am, we were both tired, there were NO cars at all for miles. Actually at the same time i was writing an essay from my English class on my iphone and then saw cop lights behind us Now my licence is suspended)

What does this accord have in it for hop-ups? The E46 M3 is quite fast.

cold air intake, custom(world's only) true dual exhaust, cat delete, lost some weight, port and polish manifold and runners. So pretty much stock.

There is no way that Honda is faster than an M3 then. Maybe a 325 or 328, but it's not even in the same league as an M3. I mean, it's not even debatable. Ok you can get back to your crack pipe now.

Eventually the filter will get saturated enough that it starts pulling in water, or during winter it could become encrusted with ice and choke the engine.
This is probably the worst and most excessive amount of misinformation I have ever heard on a forum, and honestly, I have heard a bunch over the years.

Th filter will not suck up a "drop hear a drop there" and wreck your motor. Try and have an understanding of basic physics and fluid dynamics before making a post full of obscene internet rumors.

The CAI you made is purposeful in only one way that I can see. The plastic will not hold heat in like a metal tube, and the filter will allow cold air draw away from the hot engine. The issue is the ridges in the plastic flex tubing. If the flow would bypass these, you are losing the depth of the ridged part times 2, effectively reducing the intake tract. What you could do to totally fix this issue, is now spend the money and get mandrel bent tubing the shape and size of your intake, and then you would have a worth while endevour.

Props for making it, but you can do better.

And just to set the record straight, I am aware of hydrolock. Most cases involve driving into a puddle large enough to completely submerge the filter, making the water the only viable substance to go it, and it must be for more than a little splash on a road.

I have a very hard time believing anything posted here. The thought that a mist of water while driving is going to hydro lock the motor is almost as silly as the last guy that said it.

You seem to have a slight grasp on fluid dynamics, but your theory is off...

Air is a fluid, and can travel faster and easier through the pipe than the water. He would require an extreme amount of pressure to allow a heavy object (such as water) to travel through a crinkled tube all the way through the throttle body and into the motor.Not only are the ports on the inside of the intake manifold at least a half inch from the floor of the manifold, the idea that the moderate amount of suction produced by the motor could make water fly into the motor over air. Fluid is like anything else, and it will follow the path of least resistance. Since air is lighter than water, air will follow the twists, and bends of the intake as there is no resistance for it to deal with. Water has added weight, and will have trouble all over the place.

First, it has to find it's way through the filter. The same filter you are asking to keep pieces of dust that measure in the microns out, you are asking to keep a drop of water... I know you said mist, but mist is still larger.

Second, once the water travels through the filter, and rejoins with the rest of itself (think Terminator 2 in the factory) the water has to be pulled through the tube, while fighting gravity, and other forces in the moving car. It has to go up and down every ridge in the tube, and then get past a throttle body, somehow find it's way airbourne, and then into a port in the motor... After that, more of the waters buddies have to show up at the exact same time so that there is more water in the engine than airspace, causing the motor to break, as water does not compress like air.

The idea that this is in anyway true from mist is laughable. Please stop posting misinformation. I mean, if you really don't understand something, 5 minutes on Google isn't going to help.

Have someone take video clips and post it. New thread, "how I locked my motor". You are not a newbie to be this defensive. Take a hint.
Honestly, I should do the experiment for you....

Take a BMW, and submerge the filter in water. To be fair, the amount of water you would get from mist is, lets say half the cone filter...

I would do that. No problem. Why? Cause it will not suck up water if there is the availability for air to be picked up first...

What part of this don't you people understand... I guess you were too busy day trading in science class...

every post i see from e39bmw relates to a honda in some way... please take it to a honda forum in regards to how you drive your car (stupidly) and how you "mod" it (gut the interior) and brag about your ricer bmw there and maybe you wont piss everyone off hear. Ive learned alot from this forum and has actually made me respect my bmw ALOT more. Im not flaming, just saying, take the crap somewhere else because its obvious the people on this forum dont want to hear you tearing up your bmw racing it down the mountain and gutting the interior to shave like .00003 seconds off a drag slip. Also 145 in rain? STUPID... 80 in snow? STUPID.. are you kidding? its almost a disgrace to our roundels..
